Question:

A biotechnology company produces a therapeutic drug whose concentration has a standard deviation of 4 grams per liter. A new method of producing this drug has been proposed, although some additional cost is involved. Management will authorize a change in production technique only if the standard deviation of the concentration in the new process is less than 4 grams per liter. The researchers chose n = 10 and obtained the following data in grams per liter. Perform the necessary analysis to determine whether a change in production technique should be implemented.
